Why Does Willpower Collapse When Stressed?

Stress doesn't drain a willpower tank because no such tank exists. When multi-lab replications tested the "depleting muscle" model, the effect came out indistinguishable from zero. What actually shifts under pressure, this analysis reveals, is the shape of the decision itself: options get scanned in jumbled order, closure arrives before all data is seen, and existing tendencies thicken rather than reverse. The evening you get bad news, you become an exaggerated version of your calm-afternoon self.

You'll learn:

- Why pre-registered replications collapsed the ego-depletion model

- How pressure amplifies your existing risk asymmetry

- Where rushing costs you and where it barely registers
